I have used Shavitz for many years & trust them to not only show up in an emergency but to be professional, knowledgeable & always on time. When my furnace died early on a Sunday, they responded. The tech, Elia, replaced my thermostat & my heat was back on. However, the furnace needed to be replaced. The Project Mgr. Krzysztof Kowal came over later that day & he was very helpful & knowledgeable as he explained the different furnaces. A new one was installed 3 days later by team Jonathan & Tim. Also both professional, knowledgeable & diligent. Worked non stop 6 hours!! They were careful coming in & out of house & cleaned up post installation so thoroughly that you couldn’t tell they were here. How could anyone Not use Shavitz. Thank you all

Shavitz Heating and Air just installed a new boiler in our home. The overall experience was excellent. It was a pleasure working with Ryan S. He was very professional, thorough, and responsive. I was particularly impressed that Ryan was present at the start of the installation. He explained everything to me and carefully reviewed the job with the installers. Ernie L., the lead installation specialist, was outstanding! Ernie was meticulous through the entire installation process. After the installation, Ernie took the time to go over the mechanics of the new boiler and the operation of our new thermostats. He patiently answered all of my questions. I was also very impressed with all of the Shavitz employees' attention and adherence to all COVID safety protocols and standards! Shavitz will definitely be our go to provider for all future HVAC needs.

Alex H was one of the best service techs I've ever had in any regard. I expected him to be thorough servicing my electric furnace because Shavitz reps have never disappointed in providing the maintenance needed. Alex was especially great in discussing variable options to help me with my heat. He was so very informative and knowledgeable, plus personable. Great experience all around. Thanks Shavitz

Great service from David. Very Knowledgeable, explaining step by step his work, offering solutions and tips. Even gave us tips on how to use a mix of water and vinegar to keep the water catcher clean. Excellent service, very courteous, very mindful with putting his shoe protection on, and kept his mask on at all times. Shavitz never fails me.

Cornelius M. serviced our AC today, as part of our annual maintenance contract with Shavitz, who we have happily used for nearly 15 years. He is an outstanding technician, like all of Shavitz's techs. He was thorough, efficient and gave me choices about what additional service and parts we needed, explaining the reasons why. He makes sure that no dirt is dragged into our house and cleans up afterwards. Enjoyed talking to him as well. We appreciate Shavitz and Cornelius and unequivocally recommend them to all our friends in Skokie.

We have used Shavitz for years and they have never failed to provide excellent service. The most recent service visit was on May 9. The technician was Cornelius M. He was courteous, competent, and efficient. At the beginning of the visit, he explained in easy to understand terms what he be doing and at the end, he explained what he had found, i.e. no problems and reviewed his work. He also arranged with the office to make our next appointment. He was outstanding and I would be delighted to have him provide service to us again.

Cornelius has been my service technition for the last two heating and cooling seasons. He has been thorough, professional, knows what he is doing and made suggestions that made sense. He recently suggested something that I said I would think about and he said fine. No pushing. I am very pleased to have him as my heat and cooling professional.

Shavitz was awesome - lousy rainy weather so they kept me informed with regular calls on the appointment status (had to work outside on compressor). Cornelius M., service technician, is a great guy. Did not push equipment, despite my unit being from 1994. Explained everything, was fast, efficient, knowledgeable, and personable. These are people you can trust, and I've had more than few that you can't! If you need something fixed or regular maintenance, my highest recommendation.
